These numbers matter more here. The Cummins/Allison engine/drive-train in these vehicles are otherwise good for 1 million miles before rebuild on average until they are used as delivery trucks. The constant stopping and starting used as delivery trucks cuts that number down to around 480k miles. So they are selling vehicles that will require engine and transmission rebuilds in less than 80k miles. That's very shady. The engine rebuilds are usually around $10k same as a refurbished engine and the transmission rebuild is around $3k. That does not count the cost to install them.
* Shocks and struts wear out
* Catalytic converters are a semi-wear item
* In winter states that use salt, rust absolutely destroys things. I've had the exhaust system rust through on all of my vehicles (simply happens with age).
* Seat cushions, steering wheel, and other high touch surfaces wear. Likely not an issue _now_, but means a few years down the road, these things will be broken.
* Engine accessories - belts, starters, alternators, pumps, etc. Everything is just a bit closer to it's failure point.

Most of these issues aren't particularly expensive on their own, but they add up. Further, your expected maintenance is wildly different.
Liquid magnesium chloride is the goto in most states now, and you’ll be happy to know it’s even worse!
Sodium chloride attacks exposed metal pretty badly.
Magnesium chloride seems to attack powdercoat, e-coat (electro dipped, all cars parts), and nickle coatings, as well as clear coat wet paint seemingly worse. Which then leaves spots exposed to rust. It seems to hang on to the vehicle and attack the entire winter. I’ve found that areas that switch to mag chloride have worse looking vehicles, so, imo, worse.
It’s also pretty awful for the environment.
